I'll handle this one since you posted this, thanks! The down arrow can be used for any reason it doesn't belong (incorrect, sexist, etc.) - once you hit that, a popup appears where you can write a comment. I review every single one of those, and I can rip them out at that point!
Happy to say that this is the first time I've had a sentence like this reported, so it's not too much of a problem. Please use the arrow to report any others you see!
